Scope and Field of Application |
The Service centralization and continuity application server (SCC AS) is the entity in the IMS domain that handles the management of the access transfer of active sessions. The SCC AS coordinates the proper media and signalling exchange to the access network in which the UE is present. IMS centralized services (ICS) allow for centralizing IMS services regardless of whether the mode of the mobile network is circuit-switched (CS) or packet-switched (PS). The ICS function introduces a new entity in the IMS network, the service centralization and continuity application server (SCC AS). The SCC AS entity combines the SIP signalling and acts as a back-to-back user agent (B2BUA), providing an anchor point for incoming and outgoing calls. This conformance test specification aims to verify the SIP Protocol over the ISC reference point. | ||||||
